Caudal duplication syndrome in an adolescent: Rare concoction of duplication anomalies.

Caudal duplication syndrome is a rare and interesting entity with a reported prevalence of <1/100,000 births. Caudal duplication syndrome encompasses a diverse spectrum of anomalies primarily involving partial or complete duplication of organs comprising the gastrointestinal, genitourinary and distal neural tube systems. The term 'caudal duplication syndrome' was coined by Dominguez et al. in 1993, in a case series of six patients presenting with findings pertaining to duplication anomalies of genitourinary system, hindgut, lumbosacral spine and cord. We here report a unique case of caudal duplication presenting in late adolescence and briefly review the available literature on this rare abnormality.
